Item13228: jsonrpc fails with no method if Apache2::Request is installed.

Foswiki appeared to be working fine under ModPerl, until the recommended Apache2::Request module was installed.

Once enabled, jsonrpc requests all fail with "Invalid JSON-RPC request - no method"

The underlying problem is that Apache2::Request does not make data available using POSTDATA. The JSON POST requests upload the application/json string as an "anonymous" upload. The proper way to handle this is to open a stream handle against the Apache2::Request object, otherwise the data is just not available.

Digging down through the Engine::Apache code, it does detect the json data as an upload, but because there is no filename key associated with the data, the Foswiki upload mechanism cannot open a stream against the file. If down in the Engine::Apache::prepareUploads() method I detect the case of an upload without any filename keys, and issue a direct read against the request, it returns the json data without any problem:

+        #else {
+        #            $this->{query}->read(my $data,  $contentLength );
+        #            print STDERR Data::Dumper::Dumper( \$data );
+        #            
+        #}

However by the time JsonRpcContrib::Request gets the request object, it doesn't have a read() method and there does not appear to be any way to get the posted data.

Fixed, but needs review by someone more familiar with mod_perl
